Since 1958, the Mark V has been earning its stripes with proven performance as "the world's strongest bolt action," and nothing has changed with the introduction of this Mark V Accumark .300 Weatherby Rifle. From the rock-solid receiver to the durable 3-rings-of-steel design, it offers unrivaled out-of-the-box accuracy and high-end performance. In fact, Weatherby believes in their rifle so much they guarantee you can shoot a 1.5" 3-shot group at 100 yards right from the box!
